I installed kubuntu 15.04 and upgraded it to 15.10. I was able to boot normally into kubuntu a few times but suddenly it started to boot only in emergency mode showing this:

[    2.932200]Error parsing PCC subspaces from PCCT
[    3.245398]nouveau ![  DEVICE][0000:06:00.0] unknown Maxwell chipset
[    3.245406]nouveau E[  DEVICE][0000:06:00.0] unknown chipset, 0x118010a2
[    3.245410]nouveau E[     DRM] failed to create 0x00000080, -22
welcome to emergency mode! blablabla...

I reinstalled it all, it worked normally but after some reboots, it's back and this error is showing again :( I also searched in the great internet. Found some things about adding "nomodeset" to grub but it didn't make it.

Thanks in advance for any help!

My laptop is a Lenovo ThinkPad Yoga 15 (20DQ/003QMZ)
Graphics: Intel HD Graphics 5500, NVIDIA GeForce 840M

Solved by disabling fast startup on Windows 10 (dual installation).

To achieve that in Windows open the Control Panel, go to All Control Panel Items > Power Options > System Settings > Change settings that are currently unavailable (UAC) and uncheck Fast Startup (recommended).
